Hair Clip

ABSTRACT

A hair clip comprises a lower clip piece that contacts on and/or slide over customer&#39;s hair, an upper clip piece, and a finger pivotally connected to the upper clip piece. The finger has sidewalls, extensions extending from the sidewalls, a stopper that limits the pivoting of the finger, and side flaps that extend beyond the stopper. The upper clip piece, the lower clip piece and the finger form a space that temporarily grabs a customer&#39;s hair for hair styling work. The side flaps prevent unwanted trapping of customer&#39;s hair between the finger and the upper clip piece. In addition to teeth provided on the upper clip piece and the lower clip piece, teeth are provided along the entire length of the finger, along the sidewalls, extensions and flaps of the finger thereby providing easy and firm grabbing of hair.

BACKGROUND OF THE INVENTION

1. Field of the invention

The invention is related to a hair clip. More particularly, the present invention is related to a hair clip that greatly simplifies the task of temporarily grabbing strands of hair for hair styling without unwanted trapping of hair during hair styling.

Hair clips are used to help hair stylist's work for temporarily grabbing or holding strands of the customer's hair during hair styling including hair extension work. Hair extension work is very labor intensive and requires high level of skill and care at the same time. An hair clip that reduces the costly labor and fatigue of a hair stylist while meeting the delicate requirements of hair styling has long been in need.

2. Description of the Prior Art

Korean Patent No. 20-0373108 by Chan Soo Kim discloses a hair clip that has an upper clip piece, a lower clip piece and a finger that is pivotally connected to the upper clip piece. A disadvantage of the hair clip is that a customer's hair tend to be accidentally trapped between the finger and the upper clip piece when a hair stylist uses the hair clip. Another disadvantage of the hair clip is that the rear end of the finger protrudes high from the upper clip piece and bothers the hand or finger movement of a hair stylist.

DESCRIPTION OF PREFERRED EMBODIMENTS

FIGS. 1 and 5 show a hair clip 10 comprising a lower clip piece 12, an upper clip piece 14 and a finger 16. The lower clip piece 12 is adapted to contact on and/or slide over a customer's hair. The lower clip piece 12 comprises a pivot end 18 and a free end 20. The upper clip piece 14 comprises a first pivot end 22 and a second pivot end 24. The first pivot end 22 of the upper clip piece 14 is pivotally connected to the pivot end 18 of the lower clip piece 12.

FIG. 3 and FIG. 5 shows that the finger 16 comprises a left sidewall 26 and a right sidewall 28, a cover 30 comprising a free end 32 and a pivot end 34, a left extension 36 that extends from the left sidewall 28, a right extension 38 that extends from the right side wall 28, a stopper 40 that connects the left extension 36 and the right extension 38 and rests on the upper clip piece 14, a round left flap 42 that extends from the left extension 36, and a round right flap 44 that extends from the right extension 38. The cover 30 connects between the left sidewall 26 and the right sidewall 28. The pivot end 34 of the cover 30 is pivotally connected to the second pivot end 24 of the upper clip piece 14.

As shown in FIG. 5, the distance d2 from the pivot end 34 of the cover 30 to the curved round edge of the left flap 42 and the distance d2 from the pivot end 34 of the cover 30 to the curved round edge of the right flap 44 are bigger than the distance d1 from the pivot end 34 of the cover 30 to the stopper 40. The round left and right flaps 42, 44 prevent stray hair from being trapped between the finger 16 and the upper clip piece 14. For example, when a hair stylist grabs a customer's hair with the hair clip 10 and moves the hair clip 10 along the grabbed hair, the flaps prevent other hair from being trapped between the joints of the moving parts of the hair clip. The distance d2 means the distance between any point on the curve of the left and right flap 42, 44 and the pivot end 34.

The hair clip 10 further comprises a lower thumb piece 46 extending from the pivot end 18 of the lower clip piece 12, a upper thumb piece 48 extending from the first pivot end 22 of the upper clip piece 14, a first pivot spring 50 installed at the first pivot end 22 of the upper clip piece 14 and urges the upper clip piece 14 toward the lower clip piece 12, and a second pivot spring 52 installed at the second pivot end 24 of the upper clip piece 14 and urges the free end 32 of the cover 30 away from the lower clip piece 12.

The stopper 40 comprises a flat stopper bar 54 that comprises an upper stopper surface 56 and a lower stopper surface 58. The upper stopper surface 56 is tangent to the curved round edges of the left flap 42 and the right flap 44.
